do you know if the throttle bodies between a 305 and a 350 are different?

RE: argon do you know?
 

no..but the injectors in em may well be...I know a 454 has a different injector....easy enough to swap though

RE: argon do you know?
 

minus the price of course :D

If ya take it apart,replace the fuel reg./...just about all of em on tbi's drip

RE: argon do you know?
 

well what it is, the injectors seem to have a more delayed injector pulse especially at idle than they used to. also hearing some kid of vacuum leak coming from around the tbi, i knoticed the throttle bore has gotten really dirty. everything else in the fuel system is new. so im thinkin a new throttle body with 350 injectors in it.

may be...
but I think the hiss is the base gasket...common on those...and 2 injectors and a fuel reg....and thats all the "wear" parts on it

RE: argon do you know?
 

i dont think its the base gasket, ive replaced the base gasket 2 or 3 times now and its still there.

RE: argon do you know?
 

ok..do you hear the hiss with the breather off?...they will suck prett loud.

could be the throttle shaft,I guess

RE: argon do you know?
 

yes its worse with the breather off, i didnt notice this hiss until the time i started having a cold idle problem
